Abstract
All of the reaction cross sections, angular distributions, energy spectra, and double-differential cross sections are consistently calculated and analyzed for the neutron-induced 46,47,49,50,nat.Ti reactions below 20 MeV. Concurrently, the present work uses the optical model; the unified Hauser-Feshbach theory; the exciton model, which includes the improved Iwamoto-Harada model; and the distorted wave Born approximation theory. Especially, the recoil effect is taken into account in the calculation to keep the energy balance of whole reaction processes. Theoretical calculations are compared with existing experimental data and other evaluated data in ENDF/B-VIII, JENDL-4, and JEFF-3 below 20 MeV. Our theoretical calculated results agree with the experimental data and give a better description than the other evaluations for all reactions.
